As mentioned previously, the accuracy problem is due to the incorrect
definition of the value of PI in the Aztec C include files.
No, the Amiga does not come with a floating point coprocessor. The
MicroBotics 2 Meg memory card supports the '881, and the 68020
adapter has a socket for one. It is not however standard equipment
(don't I wish).
